OAR-LOOK.

Application filed August 15, 1906, Serial No. 330,671.

Specification of Letters Patent.

Patented July 6, 1909.

Renewed October 28, 1908. Serial No. 459,935.

To all whom it may concern:

Be it known that I, THoMAs W. CAREY, J12, a citizen of the UnitedStates, and a resident of the city of New Orleans, in the parish ofOrleans and State of Louisiana, have invented a new and ImprovedOar-Lock, of which the following is a full, clear, and exactdescription.

My invention relates to oar-locks, and the purpose of the invention isto improve upon the construction of oar-lock for which application forLetters Patent was made by me October 19th, 1905, Serial No. 283,419,and allowed June 2, 1906, the improvements consisting in the materialsimplification and lightening of the construction without detractingfrom its strength, together with an improved means for regulating therotation of the oar in its bearings, and for regulating the dip of theoar.

It is also a purpose of the invention to render it possible to assembleor to disconnect the various parts much more conveniently andexpeditiously than under the allowed construction above referred to.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a portion. of the body of a boat and itsoutrigger, and a side elevation of the improved oar-lock in position onthe outrigger, the sweep or oar being in section Fig. 2 is an enlargedsectional side elevation of the oar-lock, the oar or sweep being intransverse section; Fig. 3 is a section taken practically on the line 33of Fig. 2; Fig. 4 is a section taken practically on the line 14 of Fig.2; and Fig. 5 is a vertical section through a modified. form of thesocket member of the device, the section corresponding to that shown inFig. 2.

A represents a side of a boat and B the outrigger attached. thereto,longitudinally upon which outrigger the base plate 10 of the improvedoar-lock is bolted or otherwise secured. The body C of the oar-lock is aring body and is made in two sections, a lower section 0 and an uppersection 0, the two sections being connected at one of their opposingends by a hinge 11, as is shown in *igs. 1 and 2. At the opposite end ofeach section correspondingly slotted horizontal lips are integrallyformed, adapted when the sections of the said ring body are closed toengage one with the other, and the upper lid is designated as 12 and thelower one as 13. A bolt 14 provided with a wing nut 15 is pivoted in theslot of the lower lip 1.3, and when the sections of the ring body are tobe held closed the bolt 14 is carried. vertically upward into the slotin the upper lip 12 and the nut 15 is screwed to a firm bearing uponsaid lip as is best shown in Fig. 2.

At the hinge end of the lower body section 0 a bearing surface 16 isprovided in the form 1 of a fiat disk, as is particularly shown in Fig.2, and from the center of said bearing disk 16 a pintle 1.7 extendshorizontally outward, and said pintle is provided with an externalannular groove 18 and a rounded outer end or head 19. A band D isadapted to turn in the ring body 0, and said band is preferably muchwider than. said body so as to extend beyond the side faces of the body.The band D is firmly attached to the handle of the oar or sweep E bymeans of screws or their equivalents, and the said oar-band is providedwith a centrally-located exterior rib 20 that extends into acorresponding groove 21 in the inner face of the ring body 0 when thesections of the body are closed upon the said band as is also shown inFig. 2.

A socket F is provided for the ring body (1. This socket consists of avertical member 22 and a horizontal member 2-3, both of which membershave chambers therein, but the chambers of the two members do notintcrsect, and the chamber of the vertical member 22 extends throughfrom top to bottom. The upper end of the chamber in the member 22 of thesocket F is conical to receive a cone bearing nut 25, which is securedupon the upper threaded end of the bolt 26, the lower end of which boltis likewise threaded. After the bolt has been passed up through the saidchamber in the member 22 of the socket, a cap nut 27 is screwed upon itsupper end so as to hold the conical nut firmly to its seat. 'lhisconical nut serves to cause the said socket F to turn more or lessloosely on the bolt 26 which is the pivot pin for the said socket.

At the lower end of the vertical member 22 of the socket F a largehorizontally located circular chamber is formed, in which chamber alining 26' of hard metal is located, as is shown in Fig. 2, and thebottom of this lower circular chamber is open, but said chamber isclosed, when the bolt 26 is in position in the socket F, by means of theaforesaid base plate 10, which is attached to or constitutes an integralportion of the bolt 26, and just above said base plate 10 a conicalsection 10 is formed on the said bolt, as is also shown in The lowerportion of the bolt 26, or that portion which is below the base plate 10is adapted to pass through the outrigger B or through the gunwale of theboat, and is held in its set position by a nut 28 followed by a lockingnut 29; and in the chamber at the bottom of the said vertical member 22of the socket F balls or rollers 30 are usually placed, which havebearing against the cone section 10 of the bolt 26, the lining 26 of thelower chamber in said socket and the upper face of the base plate 10, sothat the said socket F may turn around the bolt 26 with the least amountof frictional contact between its bottom surface and the said baseplate. But if desired the ball bearing chamber may be omitted and thebase plate 10 may be brought to a direct bearing with the bottom of thesocket F, as is shown in Fig. 5.

A chamber in the horizontal member 23 of the said socket F is adapted toneatly receive the pintle 17 extending from the ring body C, as shown inFigs. 2 and 3, but the chamber in said horizontal member 23 of thesocket F is provided with a pocket 31 at its bottom portion, whichcommunicates directly with said chamber, and a fin 32 formed integralwith or attached to the pintle 17 extends down into said pocket. Thisfin is adapted to regulate the dipping action of the oar and is used inconnection with opposing screws 33, which are made to enter the pocket3] from opposite sides of the said socket member 23 as shown in Fig. 3,and each screw is provided with a controlling nut 34.

The pintle 17 of the ring body C is held to turn in the chamber of thesocket member 23 by passing a bolt 35 through the said member 23, andthrough the groove 18 in the said pintle as is shown in Figs. 2 and 4,which bolt 35 is provided with a head at one end and a nut at theopposing end.

A regulating bolt 36 is passed through a slot 36 in the upper centralportion of the upper section 0 of the ring body C, which regulating boltis provided with a rectangular head 37, loosely fitted in the groove 21in the said ring body, and is further provided at its outer end portionwith a nut 38 and accompanying Washer. The head of the bolt 36, which isadjustable in the slot 36 is adapted to be engaged by a pin 39 extendingfrom the rib 20 on the oar-band D, and when such an engagement takesplace it signifies to the oarsman that the blade has reached the properposition for planting or dipping the same in the water to make a stroke,and said time is regulated by the adjustment of the said bolt.

It is obvious that the improved oar-lock is well adapted for the purposeintended, since the ring body C is capable of turning in the socket Fand the socket F turns around its ivot bolt 26, while the car or sweephas limited rotary movement in said ring body C.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent,-
